- HUMIDIFYING APPARATUS.

Specification of Letters Patent.

Patented Mar. 16, 1920.

To all whom it may concern:

Be it known that I, ADoLPH \V. LISSAUER,

a citizen of the United States, and a resident of the city, county, andState of New York, have invented a new and Improved HumidifyingApparatus, of which the following is a full, clear, and exactdescription.

An object of my invention is to provide a unitary structure'of ahumidifying apparatus which houses the thermal means necessary for thehumidifying apparatus.

Another object of the invention is to provide an apparatus of the classdescribed which is simple in construction, easily accessible andinexpensive to maintain.

In the accompanying drawing forming part of the application, Figurerepresents a diagrammatic, sectional view through an apparatus embodyingmy invention.

Fig. 2 is a cross-section on line 2-2, Fig. l.

It is common to supply liquid by gravity that is to be treated thermallyand it is customary in some types of humidifiers to provide an overflowby means of nipples rising from the bottom of the sump of thehumidifier. These nipples direct the overflowing liquid on to the meansfor thermally affecting the condition of the liquid. The difficultyencountered in such type of overflow is that it is nearly impossible tohave all the nipples exactly on the same level. However, even though itwere possible to set all the nipples to a common level the movement ofthe liquid circulated through the humidifier disturbs the originalrelation of the nipples and therefore the efficiency ofthe appa- I ratusis decreased.

To overcome the above defects I provide a series of weirs 3 formed. in arising partition 4 disposed in front of the separator 5. This partition4 rises suliiciently above the bottom of the separators to form with therear wall f the humidifier a sump 7, below the separator 5 into whichthe separator 5 discharges. p

The mist formed-by nozzles 8 that drops before reaching the separatorsis conveyed by an inclined bottom section 9 of the humidifier, to thesump 7.

The weirs 3 discharge into troughs 10 which are disposed above coils 11.,The liquid from the troughs drips on said fcoils to be aflectedthermally thereby. The coils 11 and troughs 10 are housed in a section12 of the humidifier structure, which section forms the intregal part ofthe entire apparatus and is disposed below the bottom of the humidifyingapparatus, which bottom as previously described is formed by the sumpand the inclined bottom section 9. The weirs 3 being located in thepartition 4 their level can be located at will and their relation willnot be disturbed by the fiow of 'the liquid for the reason that they areformed in the wall section which is disposed vertically and its lateralfluctuation cannot materially affeet the relation of the weirs andtherefore the efiiciency of the apparatus. The deformation of the bottomthat may be caused by the flow of the liquid can in no way affect therising partition wall a and therefore the relation of the weiis. Itwill, be evident therefore that the outflow of liquid from the weirswill remain constant with the exception that different quantities ofliquids may be used from the sump 7 or the section 12 to obtain thedesired mixture in the mixing valve 1-4, which will supply the samequantity of liquid, although the proportions of which may differ, to thenozzles 8.

The mixing valve is connected to section 12 by a conduit 15 and to thesump 7 by a conduit 16, also a conduit 17 connects the mixing valve tothe pump. The quantity of liquid flowing from the sump and from section12 to the mixin valve is controlled by a diaphragm 18 wh1ch is affectedby the thermostats 19 and 20 located respectively in the air inlet 21and the passage of the separators.

I claim:

1. In a humidifying apparatus an air chamber through which an aircurrent may be passed, means for supplying moisture to the air current,means for eliminating the excess of moisture supplied, a sump about themeans for eliminating the excess of moisture, said sump having weirs inone of the sides, troughs disposed below the sump for receiving liquidfrom the weirs, means for affecting thermally the liquid disposed belowthe troughs and onto which the troughs are adapted to discharge, meansfor vmixing the liquid from the sump and that affected thermally; saidlast means being connected to the means for supplying moisture to theair current.

2. In a humidifying apparatus an air chamber through which an aircurrent may I be passed, means" for supplying'moisture to weirs in oneof itssides for feeding gravitationally. the excess of moisture, ontothe means for thermally affecting the moisture, and means for mixin theexcess of moisture in the sump, and t at affected thermally,

the said last meansbein'g connected to the means for supplying moistureto the air current.

3.-In a humidifying apparatus, an air chamber through which an aircurrent may be passed, means for supplying moisture to the air currentin the chamber, separators for eliminating the excess of moisture, apartition disposed in the chamber transversely of the direction of airflow, and in front of the separators, said partition forming with thewalls-of the chamber a sumpabout the separators, said partition havingweirs forming an overflow for said sump, and a bottom section in said.air chamber resting on the partition, and disposed to direct a flow ofliquid into the sump. v

4. Ina humidifying apparatus, an air chamber through which an aircurrent may be passed, means for supplying moisture to the air currentin'the chamber, separators for eliminating the excess of moisture, apartition in the chamber in front of the separators, forming with thewalls of the air chamher a sump about the separators, said partitionhaving weirs forming an overflow for )said sump, and, a bottomsection-in said air chamber resting on thepartition and sloping towardit so as to cause a flow'of liquid into the said sump over saidpartition.
